“Do 你 know Bradley Whitford?" Tennant asked the crowd. "He’s my American Doctor.” Of course! Whitford played Josh Lyman, the brilliant but frantic deputy chief of staff from the West Wing. Tennant is a passionate 粉丝 of the show.

"This could be my final 年 – it's terrifying. I 爱情 Doctor Who but it can be quite an insular world and I do want to do other things. There will come a time when this is over... But I knew that when I started."

First off, what a strange and poetic way to begin this superb finale. Perhaps we were expecting it to begin with fireworks on Gallifrey. A showdown between the Doctor and the Time Lords for the eternity of suffering they’ve caused him.
